This mountainous Balkan country is dominated by the Dinaric Alps, whose karst geology has created dramatic limestone formations, deep river canyons like the Tara River Canyon (Europe's deepest), and numerous caves. The central and southern regions feature high plateaus and mountain peaks exceeding 2,000m, while the northeast contains the fertile Sava River valley plains. A short 20km Adriatic coastline near Neum provides access to the sea, but most of the country is inland, with major rivers including the Neretva, Drina, and Una cutting through spectacular gorges and valleys dotted with medieval fortresses.
